Moth‐Wing‐Inspired Multifunctional Metamaterials

open access: yesAdvanced Materials, EarlyView.
This study develops a moth‐wing‐inspired heterogeneous metamaterial that achieves synergistic broadband sound absorption, mechanical energy dissipation, and thermal insulation within a lightweight architected framework. Combining bioinspired gradient design, genetic‐algorithm optimization, and additive manufacturing, the bionic heterogeneous acoustic ...

Hunting‐mediated predator facilitation and superadditive mortality in a European ungulate

open access: yesEcology and Evolution, 2018
Predator‐prey theory predicts that in the presence of multiple types of predators using a common prey, predator facilitation may result as a consequence of contrasting prey defense mechanisms, where reducing the risk from one predator increases the risk ...

Impact of fear in a prey-predator system with herd behaviour

open access: yesComputational and Mathematical Biophysics, 2021
Fear of predation plays an important role in the growth of a prey species in a prey-predator system. In this work, a two-species model is formulated where the prey species move in a herd to protect themselves and so it acts as a defense strategy.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

open access: yesAdvanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Impact of disease on a two-patch eco-epidemic model in presence of prey dispersal

open access: yesComputational and Mathematical Biophysics, 2022
The present model is dealt with prey-predator interactions in two different patches where only prey species are allowed to disperse among the patches.

On the Lyapunov functional of Leslie-Gower predator-prey models with time-delay and Holling's functional responses [PDF]

open access: yes, 2012
The global stability on the dynamical behavior of the Leslie-Gower predator-prey system with delayed prey specific growth is analyzed by constructing the corresponding Lyapunov functional.

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

open access: yesAdvanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

Predator–prey Systems with Mites1)

open access: yesEPPO Bulletin, 1979
AbstractPopulation models of fruit tree red spider mite and predatory mite are given, which are used to explain the regulation of spider mites by predatory mites and may be used to manage spider mite systems in apple orchards.The models are based on extensive experimental knowledge of the bionomics of prey and predator.

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

open access: yesAdvanced Materials Interfaces, EarlyView.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Model Predator Dan Prey Dengan Model Susceptible - Infected – Susceptible [PDF]

open access: yes, 2010
A predator-prey model with infected prey is an interaction between a predator and a prey population with infected prey. This model is a result of the predator-prey model with logistic growth in the prey population which is combined with Susceptible ...
